UNITED STATES PATENT OFFIC GEORGE l1. AVERY, OF EAST HAMPTON, ASSIGNOR OF ONE-HALF TO THE N STANDARD VHIP COMPANY, OF VESTFIELD, MASSACHUSETTS.

BAND-UNITING DEVICE.

SPECIFICATION forming part of Letters Patent No. 465,652, dated December 22, 1891.

Application filed April 10, 1891.

T aZZ whom, it may concern.-

Be it known that I, GEORGE ll. AVERY, a citizen of the United States, residing at East Hampton, in the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Band-Uniting Devices, of which the following is a specification. a

This invention relates to devices for unitto ing-the ends of round leather and other similar bands, the object being to provide improved means for connecting such bands end to end by joint devices which form a substantially permanent union of the parts and which present no inconvenient enlargement of the joint; and it consists in thepeculiar construction and arrangement of the joint-connecting parts, all as hereinafter fully described, and pointed out; in the claim.

In the drawings forming part of this specification, Figure 1 is a side elevation, partly in section, of two parts of cylindrical banding placed end to end and united by devices embodying my invention. Fig. 2 is a similar View to Fig. 1, but showing the enduniting devices thereon in different positions from those shown in Fig. 1. Figs. 3 and 4. are perspective views of the joint-uniting parts. Fig. 5 is a similar view to Fig. 1, but showing 0 a somewhat different form of band-uniting hook from that there shown. Fig. 6 shows in side elevation the hook employed in Fig. 5. Fig. 9 illustrates still another form of hookfastening, which may be employed in place 5 5 of those shown in the preceding figures,

which is fully described below. Fig. 7 illustrates the manner of employing a wire-loop fastening for uniting the ends of the bands, and Fig. 8 shows a side elevation of said lastnamed fastening.

In the drawings, B 1-3 indicate parts of cylindrical banding of leather or similar material, such as is in common use for driving light machinery, and for bell and signaling cords in cars and similar vehicles.

1) indicates a metallic hook, which is formed from a staple D, (shown in Fig. 3,) and which serves, directly, as one means for uniting the ends of said band parts, as shown in Figs. 1 and 2. The ends of the band parts B, which are to be united by the hook D, above referred Serial No. 338,345. (No model.)

to, are first perforated transversely to receive each one of the legs of the staple D, and after said legs, which are longer than the diameter of the banding, shall have been passed through said perforations their extremities are bent toward each other in lines substantially parallel with the axial line of the banding, thereby forming a hook on each end of the staple-bar, firmly engaged with each end of the banding B. The bar of the staple and the extremities of said two hooks formed thereby are forced into the surface of the banding to or nearly to a plane with said surface, as shown in Figs. 1 and 2.

Fig. 5 illustrates a hook c, which is formed from wire which is first passed through one end of the banding, and then the same has its extremities bent to extend beyond the end in which it is inserted, and has formed on said extremities two short hooks o, between which the opposite end of the banding B is inserted, and the hooks o are then forced into the end of the banding B, over which they extend, as clearly shown in Fig. 5. Fig. 9 7 5 illustrates the same arrangement of two adjoining ends of said banding B and two double-ended hooks an, engaging in the opposite sides of the ends of the banding.

Fig. 7 illustrates a manner of uniting the ends of the banding B by a wire loop, which is passed through the ends of the banding and has the ends of the wire composing the loop twisted together, as shown in Figs. 7 and S, and all forced into the surface of the banding, so that they shall not project therebeyond.

A indicates a metallic sleeve, which is adapted to be drawn over the ends of the banding after the same shall have been fastened together in any of the above-described ways of securing the same. The said sleeve A is of substantially the same diameter internally as the banding on which it is placed, said sleeve beingdrawn from the position on 5 the banding shown in Fig. 2 to that shown in Figs. 1, 5, 7, and 9 after the ends of the banding shall have been united by either of the fastening devices illustrated in the several figures of the drawings to which reference 10: has been made, and the ends of the sleeve A, after having been brought to a position over lit the united ends of the banding and the fastening thereof, are crimped into the surface of the banding, each side of the joint thereof, as shown at 0 o in Figs. 1, 5, 7, and 9, th reby firmly securing the sleeve in its position over the joint-uniting devices, so that it cannot slip out of place. Said sleeve A serves to hold either the hooks D c :0 or the Wire fastening 6 so firmly inclosed or protected that said fastenings cannot become disengaged from the ends of banding.

In practice the sleeve A and its inclosed fastening devices are made sufficiently short to occasion no inconvenience when the banding united by such fastening devices is used for driving pulleys of small diameters.

What I claim as my invention is A round band having a uniting device consisting of a staple-like fastening forced into,

uniting, and extending longitudinally across 20 a portion of the contiguous abutting end portions of the band and having its ends embedded, and an independent metallic sleeve completely inclosing said band ends and the fastening set forth, the ends of said sleeve being circumferentially forced inward completely to cover the ends thereof and engage the band to obviate projecting edges and movement of the sleeve, said inwardly-forced ends of the sleeve being substantially beveled or inclined gradually to avoid obstruction in the travel of thebelt, all combined substantially as described.
